I have seen your work in progress on deviantART. As a self-proclaimed animator, I admire the time you spent to craft this animation. The animation is smooth with enough frames, the graphic is crisp with clean lines.
However, this animation suffers a major problem: it failed to connect the audience with the emotions you try to communicate.
I assume the idea was meant to show that the girl was overwhelmed by the boy's overly nice gestures with flowers, and became panicky and acted contradictorily. But in your animation, the girl didn't express any interest toward to the boy, and the boy was just unconditionally receiving the physical abuse, there is no hint of love connection between the two in the animation.
Another thing is the movements of the characters, while the animation is smooth with decent frame rate, the actions are a bit stiff. Adding more lead-in and lead-out movements with exaggerated morphing on the limbs would have improve the actions...
Anyway, it takes a lot of patience and effort to complete frame-by-frame animation like this. Looking forward to see more of your works!
